I have problem with my 520d 11/2000. About month ago remote key fob stopped working and I thought that battery is dead. I changed battery to new one and paired key fob with car using method (run->off -> 3 three times lock button, when unlock button is pressed down), car locks and open locks for sign of successful pairing.

After this I tested key, it works if I press lock button or trunk button, but unlock not work? At first I think that problem is in unlock button's microswitch, but I tested it using multimeter and it works fine. And I think that if fail is in microswitch, I can't pair it, because in pairing it is used. So what I can check next? Fuses I checked.

And unlock and lock works if I turn key in door's lock. Only remote unlock not work. Sorry my bad english, hope that you understand :) Thanks :)
